Trees, for example, are too large to create the force needed to push xylem upward hard enough to cause guttation. So, this cannot happen in large trees, because the pressure that is required to force the water out is too large. Pores that secrete water. So, guttation occurs during the night time. Colochasia, an aquatic plant has been found to loose more than 250 ml of water per day.

Colochasia, an aquatic plant has been found to loose more than 250 ml of water per day. When there is a high soil moisture level, water will enter plant roots, because the water potential of the roots is lower than in the soil solution.

When soil moisture is very high, water will enter the plant roots because the water potential of the roots is lower than that of the surrounding soil. Guttation occurs because plant roots actively transport ions and other solutes to the xylem that conducts water up. High amount of water in the soil where plant is grown. This is called as Guttation and takes place usually early in the morning when the rate of water absorption and the root pressure are higher while the transpiration is very low. Two lessons were learnt from this: seemingly healthy plants already had germs and bacteria appearing in guttation drops.
